I'm using IntelliJ as my editor, it has Regex search function, but I couldn't do the following : If I'm searching in a project with lots of directories for a file containing 2 phrases [ "special property" and "spin waves"], how should I write the regex ?

Here is a sample file containing these 2 phrases :

The basic idea of spintronics is to use a special property of electrons—spin—for various electronic applications such as data and information technology. The spin is the intrinsic angular momentum of electrons that produces a magnetic moment. Coupling these magnetic moments creates the magnetism that could ultimately be used in information processing. When these coupled magnetic moments are locally excited by a magnetic field pulse, this dynamic can spread like waves throughout the material. These are referred to as spin waves or magnons.

I tried : special property.*spin waves

But it didn't work.

I have an idea but I don't know how to put it in Regex, is there a way to achieve the following :

[1] I've noticed if I do a search of "special property" or "spin waves", the results are instant, but I got too many files.

[2] Even if I do a search for "special property|spin waves", it's also instant, results will have either "special property" or "spin waves".

[3] So my idea is : if the the result files are in a set X for searching "special property", and the result files are in a set Y for searching "spin waves", can I come up with a Regex that return the files that are in both X and Y ?

Search for the regular expression

(?s)(?=.*special property)spin waves

$(?s) sets the dotall flag, which allows .* to match across newlines. Then it uses a lookahead to find one of the phrases while searching for the other one normally.

Another option would be to first search for all files containing "special property" and then searching in the scope Files in previous search result for "spin waves".
